Title: Power conversion device
Inventor: NAKAMURA TOSHITAKA
IPC: H02M5/27
Filed: 1997-07-09
Abstract: PROBLEM TO BE SOLVED: To protect overload positively by judging that overload resulted and stopping a power conversion device body, when the estimation internal temperature of a power conversion element exceeds a given protection operation level. SOLUTION: A device is constituted of an overload protection circuit 40ap that is the thermally equivalent model of a power conversion element as a temperature calculation means and a comparator 42 that is a judgment means. In the overload protection circuit 40ap, a negative current detection value iup at the positive side of U phase being detected by a current detector 5a is inputted, and an estimated internal temperature Tj of the power conversion element is calculated, based on a specified ambient temperature condition Ta. Then, the estimated internal temperature Tj is compared with a specific preset protection operation level by a comparator 42 and is judged as overloading by the comparator 42 when a given value in terms of the standard of the power conversion element is exceeded and an overload signal is outputted.  Therefore, even when the output frequency of the converter becomes low, the overload of the power conversion element can be protected positively and superbly.

Title: Molding method for resin molded article
Inventor: YAMADA KOICHI
IPC: B29K105/06
Filed: 1985-08-23
Abstract: PURPOSE:To improve dimensional accuracy, by supplying a plurality of hot blanks which has been obtained by dividing and possesses different areas from each other according to the interior side and exterior side. CONSTITUTION:A hot blank 12 mounted directly on a bottom force 10 is a device forming the interior of a molded article and having a little smaller area than the surface area of the molded article. On the one hand, a hot blank 14 mounted on the hot blank 12 is a device forming the exterior of the molded article and having the area smaller than that of the hot blank 12. When compression molding is performed by lowering a top force 16, the hot blank 12 is transformed by hardly flowing the inside of a space between the top and bottom forces 10, 16. On the one hand, the hot blank 14 flows in a manner running along the top of the hot blank 12 by facing to the fringe from the central part, resulting in compression molding in a double layer state of a nonfluidized layer and fluidized layer. Therefore, a distortion based on molding is received far more by a side where a deformation quantity at the time of the molding is large, shrinkage force becomes large after cure and inward falling-down is prevented.

Title: Laser welding method and device of lap joint part
Inventor: OKABE YOSHIO
IPC: B23K26/00
Filed: 1993-06-29
Abstract: PURPOSE:To improve the accuracy of a lap joint shape and to increase a welding area in the case of tight laser beam welding of sinks, fuel tanks for automobiles, etc. CONSTITUTION:The joint parts of members to be welded are powerfully clamped and are welded by irradiating the joint parts with a laser beam 6 from an extension line 5 of the contact surfaces of the clamped and superposed welded joint parts or a line having a slight angle with this extension line 5 in the case of welding of the joint parts of metallic plates 1, 2 superposed on each other by the laser beam. The gap between the plates of the lap joint parts is thus eliminated. Since the extremely marginal point of the weld line is clamped, the distortion at the time of welding is suppressed and dislocation is prevented. Since penetration is possible broadly in the extension line direction of the contact surfaces of the lap joint parts, the welding strength is additionally enhanced.

IPC: F16L55/04
Filed: 1995-07-20
Abstract: PROBLEM TO BE SOLVED: To provide a pulsation reducing device to suppress the length of a whole and reduce the pulsation of a low frequency. SOLUTION: Pulsation in piping 1 is introduced to a pipe body 31 of a side branch 3, a part thereof is reflected by a partition plate 32 and returned to an introduction part. The other is collected, as shown by a solid line A, to one side at an upper part by the partition plate 32 and reaches a partition plate 33 through a passage 320. A part thereof is reflected and returned to the introduction part and the other is collected to one side at a lower part by a partition plate 33 and passes through a passage 330 and is reflected by a closing end 31T and returned, as shown by a broken line B, to the introduction part. Since, as noted above, pulsation is bent by the partition plates 32 and 33, the length of a passage is substantially increased and pulsation of a low frequency is reduced without increasing the length of the pipe body 31.

Title: Reproducing device
Inventor: MITSUNABE SATORU
IPC: G11B20/00
Filed: 1988-07-25
Abstract: PURPOSE:To obtain a device to prevent a main signal part, which is not desired to be reproduced, from being reproduced by providing a main signal reproducing means, a mode switching means, a sub signal detecting means, a mode switch control means and a main signal output means. CONSTITUTION:When a magnetic tape 3, to which a sub signal is recorded, contacts a head 10 and the sub signal is reproduced by a rotary head 4, a control circuit 14 switches operation to fast forward and outputs a main signal from a picture memory 16. After that, when the sub signal is not reproduced by the head 10, the control circuit 14 switches the operation to reproducing operation and outputs the main signal from a rotary head cylinder 4. In order to cancel a reproducing cut condition, a prescribed pass-word is inputted after a cancel button is operated. The pass-word is collated with storage by the control circuit 14 and when the pass-word is coincident with the storage, the reproducing operation is restarted. In order to erase the sub signal, an erase button is operated and the contents of a reproducing signal is reproduced and confirmed. Then, the button is pushed again in a desired position and erasing is stopped. Thus, when another person executes reproducing, a part, which is not desired to be observed, is automatically cut without being noticed by anyone and secrecy can be held.
